Overview
The SC250P is a piezoelectric buzzer from the Mallory Sonalert SC series, designed for industrial audio indication. It operates on AC or DC voltages ranging from 60 to 250 V and draws a current of 18 mA. The device emits a medium sound level at a frequency of 2.9 kHz in a fast pulse mode. It features internal driving circuitry and panel mounting with screw terminals. The unit has a diameter of 42.85 mm and functions within a temperature range of -30°C to +65°C.
Feature Summary
- Piezoelectric construction with integrated internal driver circuitry
- Supports both AC and DC input voltage ranges
- Fast pulse operation mode for distinct auditory signaling
- Panel mount design with screw terminal connections
Applications
- Industrial machinery status indication
- Control panel alarm signaling
- Equipment fault detection systems
Procurement Notes
Verify the specific suffix 'P' corresponds to the Fast Pulse mode and 2.9 kHz frequency when ordering. Confirm that the application voltage falls within the 60-250 VAC/DC range to ensure proper operation. Check for RoHS compliance requirements if applicable to your assembly process. Ensure panel cutout dimensions match the 42.85 mm diameter specification.
Selection Notes
Select this component when a high-voltage compatible, self-contained audible indicator is required. The SC250P eliminates the need for external drivers due to its internal circuitry. Consider the fast pulse pattern for urgent alerts where continuous tones may cause fatigue. Verify mechanical fitment against standard panel thicknesses and terminal accessibility constraints.
Part Context
This part belongs to the Mallory Sonalert SC series of industrial buzzers. These devices are characterized by their robust piezoelectric elements and ability to operate directly from line voltages without additional power supplies. The series offers various tone patterns and mounting options for diverse industrial environments.
Replacement Considerations
SC250KR (Short Pulse), SC250JR (Slow Pulse), SC250HR (Constant Tone). Substitutes must match the 60-250V rating and 42.85mm diameter. Verify terminal type compatibility before replacement.
